                <p>这里的 Handler 就是 pyspider 爬虫的主类，我们可以在此处定义爬取、解析、存储的逻辑。整个爬虫的功能只需要一个 Handler 即可完成。 接下来我们可以看到一个 crawl_config 属性。我们可以将本项目的所有爬取配置统一定义到这里，如定义 Headers、设置代理等，配置之后全局生效。 然后，on_start() 方法是爬取入口，初始的爬取请求会在这里产生，该方法通过调用 crawl() 方法即可新建一个爬取请求，第一个参数是爬取的 URL，这里自动替换成我们所定义的 URL。crawl() 方法还有一个参数 callback，它指定了这个页面爬取成功后用哪个方法进行解析，代码中指定为 index_page() 方法，即如果这个 URL 对应的页面爬取成功了，那 Response 将交给 index_page() 方法解析。 index_page() 方法恰好接收这个 Response 参数，Response 对接了 pyquery。我们直接调用 doc() 方法传入相应的 CSS 选择器，就可以像 pyquery 一样解析此页面，代码中默认是 a[href^=”http”]，也就是说该方法解析了页面的所有链接，然后将链接遍历，再次调用了 crawl() 方法生成了新的爬取请求，同时再指定了 callback 为 detail_page，意思是说这些页面爬取成功了就调用 detail_page() 方法解析。这里，index_page() 实现了两个功能，一是将爬取的结果进行解析，二是生成新的爬取请求。 detail_page() 同样接收 Response 作为参数。detail_page() 抓取的就是详情页的信息，就不会生成新的请求，只对 Response 对象做解析，解析之后将结果以字典的形式返回。当然我们也可以进行后续处理，如将结果保存到数据库。 接下来，我们改写一下代码来实现攻略的爬取吧。</p>
                <h3 id="5-爬取首页"><a href="#5-爬取首页" class="headerlink" title="5. 爬取首页"></a>5. 爬取首页</h3>
                <p>点击左栏右上角的 run 按钮，即可看到页面下方 follows 便会出现一个标注，其中包含数字 1，这代表有新的爬取请求产生，如图 12-6 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033606.jpg" alt=""> 图 12-6 操作示例 左栏左上角会出现当前 run 的配置文件，这里有一个 callback 为 on_start，这说明点击 run 之后实际是执行了 on_start() 方法。在 on_start() 方法中，我们利用 crawl() 方法生成一个爬取请求，那下方 follows 部分的数字 1 就代表了这一个爬取请求。 点击下方的 follows 按钮，即可看到生成的爬取请求的链接。每个链接的右侧还有一个箭头按钮，如图 12-7 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033611.jpg" alt=""> 图 12-7 操作示例 点击该箭头，我们就可以对此链接进行爬取，也就是爬取攻略的首页内容，如图 12-8 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033616.jpg" alt=""> 图 12-8 爬取结果 上方的 callback 已经变成了 index_page，这就代表当前运行了 index_page() 方法。index_page() 接收到的 response 参数就是刚才生成的第一个爬取请求的 Response 对象。index_page() 方法通过调用 doc() 方法，传入提取所有 a 节点的 CSS 选择器，然后获取 a 节点的属性 href，这样实际上就是获取了第一个爬取页面中的所有链接。然后在 index_page() 方法里遍历了所有链接，同时调用 crawl() 方法，就把这一个个的链接构造成新的爬取请求了。所以最下方 follows 按钮部分有 217 的数字标记，这代表新生成了 217 个爬取请求，同时这些请求的 URL 都呈现在当前页面了。 再点击下方的 web 按钮，即可预览当前爬取结果的页面，如图 12-9 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033620.jpg" alt=""> 图 12-9 预览页面 当前看到的页面结果和浏览器看到的几乎是完全一致的，在这里我们可以方便地查看页面请求的结果。 点击 html 按钮即可查看当前页面的源代码，如图 12-10 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033626.jpg" alt=""> 图 12-10 页面源码 如果需要分析代码的结构，我们可以直接参考页面源码。 我们刚才在 index_page() 方法中提取了所有的链接并生成了新的爬取请求。但是很明显要爬取的肯定不是所有链接，只需要攻略详情的页面链接就够了，所以我们要修改一下当前 index_page() 里提取链接时的 CSS 选择器。 接下来需要另外一个工具。首先切换到 Web 页面，找到攻略的标题，点击下方的 enable css selector helper，点击标题。这时候我们看到标题外多了一个红框，上方出现了一个 CSS 选择器，这就是当前标题对应的 CSS 选择器，如图 12-11 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033631.jpg" alt=""> 图 12-11 CSS 工具 在右侧代码选中要更改的区域，点击左栏的右箭头，此时在上方出现的标题的 CSS 选择器就会被替换到右侧代码中，如图 12-12 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033637.png" alt=""> 图 12-12 操作结果 这样就成功完成了 CSS 选择器的替换，非常便捷。 重新点击左栏右上角的 run 按钮，即可重新执行 index_page() 方法。此时的 follows 就变成了 10 个，也就是说现在我们提取的只有当前页面的 10 个攻略，如图 12-13 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033647.jpg" alt=""> 图 12-13 运行结果 我们现在抓取的只是第一页的内容，还需要抓取后续页面，所以还需要一个爬取链接，即爬取下一页的攻略列表页面。我们再利用 crawl() 方法添加下一页的爬取请求，在 index_page() 方法里面添加如下代码，然后点击 save 保存：</p>

                </figure>
                <p>利用 CSS 选择器选中下一页的链接，获取它的 href 属性，也就获取了页面的 URL。然后将该 URL 传给 crawl() 方法，同时指定回调函数，注意这里回调函数仍然指定为 index_page() 方法，因为下一页的结构与此页相同。 重新点击 run 按钮，这时就可以看到 11 个爬取请求。follows 按钮上会显示 11，这就代表我们成功添加了下一页的爬取请求，如图 12-14 所示。 <img src="https://qiniu.cuiqingcai.com/2019-11-27-033657.jpg" alt=""> 图 12-14 运行结果 现在，索引列表页的解析过程我们就完成了。</p>
